Replaced blower motor and performed furnace clean and tune. Removed and cleaned the flame sensor, cycled the sytem on and checked gas pressures, as well as performed a combustion test verifying no CO in the airstream. Ohmed out the igniter which did test weak. As well as noticed the inducer motor was grinding this will eventually lock up like the blower motor. Due to the age, condition, and cost to repair I highly recommend replacement of the furnace. Mr Martinez would like quotes on a new inducer motor/igniter as well as a quote for a new furnace. Second opinion scheduled with Dan F. Job complete
